stabble Stableswap Review 2026: Solana Stable Pool DEX

stabble Stableswap is a decentralized exchange on Solana. DefiLlama describes it as Solana's first frictionless liquidity and trading layer, and a May 2024 announcement calls it a DEX protocol that reduces price impact and impermanent loss risk to near zero.

The protocol has been listed since June 2024 and has its own token, STB. DefiLlama shows about $143K in TVL, down roughly 2.5% over seven days, and two audits. The TVL is small, which matters for anyone planning larger swaps or deposits.

The homepage could not be reviewed, so details such as the team, pool list, fee schedule and governance are not confirmed here. The project does not publish these in the material reviewed.

A DEX lets users swap tokens directly from their wallets using pools of assets supplied by liquidity providers instead of an order book. Stableswap pools use a formula built for assets expected to trade at nearly the same price, such as different dollar stablecoins. The formula keeps liquidity concentrated near that price, so a swap moves the price very little.

stabble applies this on Solana. It says it reduces price impact and impermanent loss risk to near zero. Impermanent loss is the gap between holding two assets in a pool and simply holding them in a wallet. It stays small when the assets stay close in price. If one asset loses its peg, the loss can be significant.

Liquidity providers deposit assets into a pool and earn a share of the fees from swaps. Traders get quotes based on pool balances. Exact pool types and fee settings are not described in the sources reviewed.

stabble does not publish swap fees, pool fees or liquidity-provider fee splits in the sources reviewed. Fees in stable pools are normally set per pool and vary with the assets paired.

Check the fee shown on the swap or pool screen before confirming a transaction. You will also pay normal Solana network fees. Any fee the protocol takes should be disclosed in its own documentation.

DefiLlama lists two audits for the protocol, but the auditors and findings are not named in the sources reviewed. Audits reduce but do not remove smart-contract risk, and a small protocol has a shorter track record to judge. No hack or shutdown is reported in the material reviewed.

Using a DEX is non-custodial, so you keep control of your keys, but deposits to pools are exposed to contract bugs and to stablecoin depegs. Regulatory status, team identity and any insurance cover are not published in the sources reviewed. Verify the official site and token address before connecting a wallet, since Solana has many copycat tokens.

stabble suits Solana traders who move between stablecoins or similarly priced tokens and care about slippage. It also fits liquidity providers who understand stable pools and peg risk. Users who need deep liquidity for large trades or want fully documented fees and team details may prefer larger, longer-established venues.
